Abstract

1338073 Area measuring machine TURNER MACHINERY Ltd 26 Nov 1970 [27 Nov 1969] 30397/73 Divided out of 1338072 Heading G1X The subject-matter is substantially the same as that of Specification 1338072, but the claims relate to the arrangement of the detectors 74. An additional embodiment is briefly described in which the light tube 26 and the photo-electric detectors 76 are replaced by switches in the output circuit of the detectors 74 so as to prevent the transmission by the detectors 74 of signals to the computing device 87 when no sheet material is detected but to allow such transmission when passing sheet material is detected.
